/* ============================================================
   CONTENT STYLES — prose pages: FAQ, reports, blog, 404, oauth,
   eurostat-check.

   Load AFTER style.css (design tokens, fonts, buttons, .site-header
   all live there). This file styles bare semantic elements only:
   prose lives in <article>, collapsible Q&A in <details>/<summary>
   — the markup needs no .content-* wrapper classes.

   Safe to load on demand inside the dashboard app (Report tab):
   the app renders no <article>, <details> or <summary> outside
   prose content, and every rule below is scoped to those elements
   or to content-specific classes, so nothing leaks into the app
   chrome.
